Human rights law imposes upon States an absolute duty not to transfer an individual to another State where there are substantial grounds for believing he or she will be tortured or subjected to cruel, inhuman or degrading treatment. This protection, called non-refoulement, emanates from a theory of human rights that recognizes rights fulfillment requires States to protect those within their jurisdiction from rights violations perpetrated by third parties, including other States. Generally human rights law recognizes that resource constraints and/or competing rights restrict protection duties. But such limitations have not been recognized in the non-refoulement context with limited theorization as to the reason.

In recent years the obligation to provide non-refoulement protection has run into conflict with the State’s obligation to protect its public from aliens suspected of involvement in terrorism. Expulsion is the traditional tool available to States to mitigate the threat posed by dangerous aliens. With this tool removed, States often lack an alternative route to mitigate this threat, with criminal prosecution and indefinite detention pending deportation not available for various reasons. The result has been numerous cases where States have been forced either to release dangerous aliens back onto the street, consistent with international law, or to find alternative means to deal with the threat in the shadow of human rights law.

This Article argues that human rights law should recognize the clash of human rights duties that arises in these transfer situations: the State’s duty protect aliens from post-transfer mistreatment clashes with its duty to protect members of the public from rights violations committed by dangerous private persons within society. Human rights law has in recent years recognized a duty on the part of States to take reasonable operational measures to protect the public from private person harms where the State knows or should know of the risk. In the case of dangerous aliens, these operational measures would presumably include expulsion. By depriving the State of the ability to expel dangerous aliens, non-refoulement protection places the human rights of dangerous aliens and the public into direct conflict.

Recognition of this rights competition is important for two reasons. First, for too long human rights scholars and bodies have dismissed the security consequences of non-refoulement as outside the concern of human rights. Acceptance that these security consequences themselves affect human rights requires consideration of how the law should address the conflict. Second, once a rights competition is accepted, human rights law prescribes a methodology for mediating between conflicting rights: balancing. A balancing approach would allow States a margin of appreciation to determine in the first instance how to choose between competing duties. The role of human rights apparatus, including national courts, international institutions and non-governmental organizations is to monitor this balance and to push States where the balance chosen appears over or under rights protective.

This Article contends that moving toward a balancing approach has at least three major advantages. First, it brings within the law both relevant sets of human rights, ensuring that the rights competition in which States are engaged is recognized by the law. This recognition allows for better monitoring by the human rights apparatus, and reduces the incentives of States to act outside of the law in protecting the public. Second, balancing reduces the security consequences for States of accepting additional categories of post-transfer mistreatment merit non-refoulement protection—a major goal of the human rights movement—thereby increasing the likelihood States will accept such future obligations. Third, by balancing the need to protect rights between both the transferring and receiving States, a balancing approach may actually lead to a more comprehensive anti-torture strategy, and therefore reduced occurrence of the practice.
